How Long Does It Take To Excavate A Construction Site

When it comes to construction, there's a lot of work that goes on behind the scenes before you can start building.

One of the essential stages of the construction process and the very first step is excavation.

Excavation isn't always easy, and it's not a particularly inexpensive step in the process, but it's vitally important.

Excavation is vital for laying the foundation upon which the structure will be built.

In the article below, we'll look at the excavation process and how long it takes to excavate a job site.

Continue reading to see what's involved in this process and what you should know about cost, timing, and how it all unfolds.

WHAT IS EXCAVATION?

Excavation is the process of moving things like earth, rock, or other materials with tools, equipment, or explosives.

It includes earthwork, trenching, wall shafts, tunneling, and underground.

Excavation has several critical purposes, including exploration, environmental restoration, mining, and construction.

Construction is one of the most common applications for excavation.

In construction, excavation is used to create building foundations, reservoirs, and roads.

Several different processes are used in excavation, including trenching, digging, dredging, and site development.

These processes will require unique techniques, tools, and machinery to get the job done right.

The process that you use will depend upon your project and what you need to build.

HOW DOES THE EXCAVATION PROCESS WORK?

Before excavation can begin, your job site must be carefully examined to ensure that the surrounding natural habitat is persevered throughout excavation.

Next, you will make plans for the site's size and depth, and the excavation contractors make drawings to mark the excavation site's boundaries.

Once these two critical steps are complete, the excavation work can begin.

The excavation process includes:

• • setting corner benchmarks

  • surveying ground and top levels

  • excavation to the approved depth

  • dressing the loose soil

  • marking up the cut off level

  • the construction of dewatering wells and interconnecting trenches

  • marking the boundaries of the building

  • the construction of protection drains

EXCAVATION BEGINS

Once there are drawings and an approved plan, excavation begins.

The excavator will use your approved plan and drawings to know where to dig.

How deep they dig will depend on several factors, like the type of foundation and if there will be a crawl space or a basement.

No matter what type of foundation you choose, it will most likely need to be placed on cement footers.

The type of foundation you choose will determine how deep your footers will be.

Below we'll take a quick look at a few foundation types and how they affect excavation and footer depth.oter depth.

SLAB

A slab is the most basic foundation type, as the name suggests.

When building with a slab foundation, you will have a wide range of options and variables available to you.

You have to be sure that your slab foundation will stand up to the local environment, like meeting frost mitigation requirements.

Requirements like this could drive the cost up to the point where it makes more sense for you to build on a basement or crawlspace.

CRAWL SPACE

A crawl space has become one of the more popular options recently.

Your crawl space will require at least 30 inches of excavation to protect the foundation from frost.

If you're building in the mountains, 36 to 40 inches is generally the minimum requirement.

If you're building a home, crawl spaces are often thought to add substantial cost savings.

This isn't the case because the bulk of the excavation cost is getting the equipment out to the site and started and then hauling away everything.

If you have to dig an additional 4 to 6 feet, it won't impact the overall cost.

BASEMENT

Basements are by far the most popular type of foundation.

Basements provide an excellent foundation system with the added benefit of extra storage space.

There are three main types of basements, including full basements, garden levels, and walkouts.

It costs more to excavate a full basement than it does the other types of foundations.

However, when you weigh the cost against the other options, the basement turns out to give homeowners the best bang for the buck.

HOW LONG DOES IT TAKE?

Keep in mind that several factors will influence how long it will take to excavate your job site, and times can vary considerably.

However, excavation for a foundation can range from 3 to 4 days on up to 3 weeks.

Generally, the worst-case scenario will involve a 10-foot over dig. This tends to happen in areas where there are large boulders, or you could get stuck in clay.
